The present invention relates to a method for operating a network comprising a primary station communicating with a plurality of secondary stations, the method comprising the primary station communicating with a secondary station in a discontinuous mode; the secondary station transmitting to the primary station a control message based on the current status of the secondary station; and the primary station changing a parameter of the discontinuous mode based on the control message.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A secondary station for use in a communication network, the secondary station comprising: a transceiver; and a processor in communication with the transceiver, the processor executing the steps of: receiving data units through the transceiver, storing the received data units in a corresponding buffer, each of the buffers having an associated quality of service requirement, recording a history of transmitting data units in corresponding buffers, estimating a time needed to transmit at least one data unit associated with a corresponding buffer within a predetermined probability of success associated with the quality of service requirement, wherein the estimated time being determined based on weighting the history of past transmissions of data units in corresponding buffers; determining whether the estimated time exceeds a threshold value; and generating a resource signal after determining the estimated time exceeds the threshold value.
2. The second station of claim 1 , wherein the quality of service requirement is based on a latency threshold.
3. The secondary station of claim 1 , the weighting represents a sliding window over the history of past transmissions.
4. The secondary station of claim 1 , wherein the weighting includes a forgetting factor, the forgetting factor weighting being less than one (<1).
5. The secondary station of claim 1 , wherein the resource is one of: a Scheduling Request (SR) and a Buffer Status Report (BSR).
6. The secondary station of claim 1 , wherein the processor further comprising: receiving the threshold value.
7. The secondary station of claim 1 , wherein the estimating a time comprises: considering a time the data is in the corresponding buffer.
8. The secondary station of claim 1 , wherein the estimating a time comprises: considering a probability density function of a granted rate of responses to a corresponding request.
9. The secondary station of claim 1 , wherein the estimated time comprises: considering at least one of: a number of packets in a corresponding buffer, a predicted number of retransmissions, a number of hops, and a granted transmission rate.
10. A primary station in a network communicating with a secondary station, the primary station comprising: a transceiver; and a processor in communication with the transceiver, the processor: storing received transmission from the secondary station associated with data units from a corresponding buffer; estimating a time need for the secondary station to deliver at least one data unit stored in the corresponding buffer with a predetermined probability of success, wherein the estimation of time is based on a decreasing weighted past receiving history of transmissions from the secondary station over time; and determining whether the estimated time exceeds a threshold value; and generating a resource signal after determining the estimated time exceeds the threshold value.
11. The primary station of claim 10 , wherein the weighting represents a sliding window over the history of past transmissions.
12. The primary station of claim 10 , wherein the weighting includes a forgetting factor, the forgetting factor weighting being less than one (<1).
13. The primary station of claim 10 , wherein the resource is one of: a Scheduling Request (SR) and a Buffer Status Report (BSR).
14. A secondary station operable in a communication network, the secondary station comprising: a transceiver; and a processor in communication with the transceiver, the processor executing the steps of: receiving data units from a primary station through the transceiver, storing the received data units in a corresponding buffer, each of the buffers having an associated quality of service requirement, estimating a time needed to transmit at least one data unit associated with a corresponding buffer within a predetermined probability of success associated with the quality of service requirement, the estimated time being determined based on a history of past transmissions of data units in a corresponding buffer, wherein a contribution of the past transmission values is altered over time; receiving a threshold value associated with a corresponding one of the buffers; determining whether the estimated time exceeds the threshold value associated with a corresponding one of the buffers; and generating a resource signal after determining the estimated time exceeds the threshold value.
15. The secondary station of claim 14 , wherein the contribution of past transmission values is weighted.
16. The secondary station of claim 15 , wherein the weighting decreases over time.
17. The secondary station of claim 15 , wherein weighting includes a forgetting factor.
18. The secondary station of claim 17 , wherein the forgetting factor has a weight less than 1.
19. The secondary station of claim 14 , wherein weighting represents a sliding window over the history of past transmissions.
20. The secondary station of claim 14 , wherein the resource grant is one of: a Scheduling Request (SR) and a Buffer Status Report (BSR).
